PATENT JAMES HocKIne, or Darren, NEBRASKA.-

SCRAPER.

SPECIFICATION forming part of Letters Patent No. 354,862, dated December 21, 1886.

. Application filed April I, 188 Serial No. 198,066. (No model.)

To all whom it may concern:

Be it known that I, JAMES HOOKING, of Denton, in the county of Lancaster and Statev of Nebraska, have invented a new and Improved Scraper, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved scraper in which the rotat-- ing shovels can be raised onlowered and the dirt deposited in a drum, which can be opened and closed by the operator.

The invention consists of adj ustable shovels mounted on a rotating frame, which can be raised and lowered, of a device for imparting a rotary motion to the rotating frame from the driving-wheel, of a device for raising andlowering the rotating frame, and of a mud-drum, which can be opened and closed.

The invention also consists of various parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure lis a side elevation of my improvement, parts being broken out. Fig. 2 is a plan View of the same, and Fig. 3 is a detail view 'of parts, hereinafter more fully described.

To a frame, A, of suitable construction, is attached an axle, B, on which are mountedtthe driving-wheels O, to the spokes of each of which is secured a grooved friction-wheel, D. On the axle B is mounted a mud-drum, E, which is open at the top and provided at the bottom with a drop-door, E.

As the devices on both sides of the scraper are the same, it will Sllffi06 to describe only one of them. To the end of the mud-drum E are attached the strips F F, on which is mounted to slide vertically the roller-frame G, having an aperture, G, which fits over the axle B. The roller-frame G is provided with pulleys H, which carry a frame, I, provided on its rim with a sprocket-wheel, I, over which passes a chain, J, which also passes over a spr0oket-wheel, J, attached to the shaft K,

' provided with a sprocket-wheel, K, which is connected with the sprocket-wheel K by the endless chain K and the wheel K is mounted on a frame, L, fulcrumed on the shaft K. A

friction-wheel, M, is attached to the sprocketwheel K, and is provided on its rim with agroove,which corresponds to the groove in the friction-wheel D. The frame L is connected by a link, L, with the crank-arm L, attached to the shaft L mounted in suitable hearings on the-rear of the frame A, and provided with the foot-lever L, to which is attached the pullspring L which holds the foot-lever L, and consequently the frame L, in place.

The shovel-frame I is provided at each end with radial arms N, to the upper ends of each pair of which is pivoted a cross-bar, N, on which is mounted a shovel, N. The crossbars N have end extensions, N, by which they are pivoted to the arms N, and a bolt, N, passes through a slot, N in each shovel-arm N, so that the shovels N can be set at any desired angle. A ring, N is also attached to the shovel-arms N, so as to strengthen the said arms in their position in relation to each other. v

The roller-frame G is provided with the straps or braces O, pivoted to an arm, P, which rests at one outer end on the roller 1?, mounted in the bracket P attached to the main frame A. The other end of the arm P is connected by the link P with a crank-arm,

Q, secured to the shaft Q, which is mounted in suitable hearings on the rear part of the frame A, and is provided with a hand-lever, R, having the pivoted pawl R, engaging the teeth of the rack R", attached to the main frame. On the shaft Q is fulcrumed a dog, S, which, when thrown forward, is placed in contact with one of the cross-bars N, so as to arrest the rotary movement of the shovel-frame.

The rear part of the main frame A is provided with the usual drivers seat, T, and to the front part of the frame is attached a tongue, U, arranged for two, three, or more horses. A bent arm, V, is attached to the frames L, and extends a considerable distance above the shovels N so as to prevent the reins resting on the said arm or cross-bar V from coming in contact with the said shovels.

The hinged door E is connected by a chain, W, and a rod, W, with. a strap, W which connects with an elbow, W, which elbow is hinged by a link, W, to abracket, W, secured to the inner surface of the mud-drum E, near the opening at the top. The elbow W when thrown upward, closes the door E by pulling on the strap W, the rod W, and the chain W.

parted to the friction-wheel M is transmitted to the sprocket-wheel K", which in turn transmitsits motion to the sprocket-wheel K by the chain K and the sprocket-wheel K, being attached to the same shaft as the sprocketwheel J, causes the latter to transmit the rotary motion to the sprocket-wheel I, attached to the shovel-frame I, so that the shovel-arms N and the shovels N will be rotated. be seen that by pressing on the foot-lever L more or less friction can be given to the contact-wheels M and D by the crank-arm L, the link L pulling on the frame L, fulcrumed on the shaft K. The roller frame. G and the shovel-frame I can be lowered by throwing the hand-lever It upward .in the direction of the arrow a, so that the crank-arm Q and its connecting-link I will lower the arm I, the roller P acting as a fulcrum and the arm 1? being connected by the strap 0 with the roller-frame G. According to the distance that the hand-lever R is thrown in the upward direction, the shovels N will engage with more or less mud, which will be picked up and held in the shovels N until the respective shovels reach their uppermost position, and then they will drop the mud into the opening on the top of the drum E. As soonasthe operator desires to empty the mud-drum he throws the dog S upward in the direction of the arrow to until itengages with one of the cross-bars N, soras to arrest the motion of the revolving frame I, and then by throwing the elbow W downward he forces the door E to open, and the mud in the drum is discharged.

The spring L, attached to the foot-lever L, has the tendency to disengage the frictionwheel M from the friction-wheel D, attached to the spokes of the driving-wheel C, as soon as the operator releases his pressure on the lever L.

The shovels N can be set at any angle by sliding the bolts N*. in the slots N of the shovelarms N, and fastening the said bolts N in the desired position.

Having thus fully described my invention,

' I claim as new and desire to secure by Letters Patent- I t 1. In a scraper, the friction -wheel D, at-

tached to the driving-wheel O, the friction- It will wheel M, and the sprocket wheels K K, mounted in the frame L, fulcrumed on the shaft K, and the chain K, in combination with sprocket I and chain J on the cutting-drum, the frame L, the link L, the crank-arm L, the foot-lever L, and the spring L substantially 6 5 as shown and described.

2. In a scraper, the friction-wheel D, attached to the driving-wheel O, the frictionwheel M, and the sprocket-wheel K, both mounted on the frame L, the, frame L, ful- 7o crnmed on the shaft .K, the sprocket-wheel K, the chain K and the shaft K, in combination with the sprocket-wheel J, mounted on the shaft K, the chain J, and the sprocket-wheel I, attached to the shovel-frame I, substantially 7 5 as shown and described.
